Abstract
The interesterification between an oil or fat and a fatty acid or between an oil or fat and another is improved by use of a lipase preparation in which lipase has been activated by water or a lower, dihydric or trihydric alcohol.
Claims9
A process for preparing a lipase preparation, which comprises the steps of:
- enzymatically reacting a lipase with an enzymatically decomposable oil or fat, in the presence of a first lipase activator and a carrier, whereby to decompose said oil or fat;
- then separating from the reaction mixture the residue of said oil or fat and recovering an intermediate lipase preparation consisting essentially of said lipase and said carrier;
- then wetting said intermediate lipase preparation with a second lipase activator, in the absence of fat or oil, to improve the activity of said lipase and form a final lipase preparation consisting essentially of said lipase and said carrier and which exhibits a high lipase activity.
